Well, to update everyone. I sent the empeg back to empeg (ha!) and they verified there was a problem with the unit - except I inadvertently caused it at some point. One of the grounding leads from the front output was burnt out, so they bypassed it with a wire. Anyway, I got it back this morning, and installed it again in my new alternator-whine-free installation. I still got the nasty feedback noises, the electronic hum, the hard drive read "ghost sound". Albeit a little more faint, they were still very audible if the volume on the empeg is turned all the way down.

Again, I removed the RCA outputs from the empeg and the noises all went away. Am I still having grounding issues with the empeg? Does anyone happen to know how I can find out if my vehicle (98 Jeep Wrangler) provides the correct ground that the empeg requires (if this sounds like a problem that would be generated by an incorrect grounding)?

Any info again?

I'm at my wits end!
